Princess Jincheng, was a revered figure of the Tang Dynasty, famed for her marriage to Tibetan King Tride Tsukten. Adopted by Emperor Zhongzong of Tang, she contributed significantly to the Sino-Tibetan relations, reinforcing the alliance initiated by Princess Wencheng.
One of her most profound contributions was her advocacy for Buddhist monks who sought refuge in Tibet. According to the Tibetan manuscript The History of Khotan Dharma (preserved in Dunhuang), Princess Jincheng played a crucial role in convincing the Tibetan king to provide sanctuary for displaced monks from Khotan. She spearheaded the construction of temples, provided living necessities, and organized translation efforts to preserve Buddhist scriptures. These actions laid a solid foundation for the flourishing of Tibetan Buddhism, particularly during the reign of Trisong Detsen.
Early Life of Princess Jincheng
Princess Jincheng, originally named Li Nunnu, was born in 698 CE during the reign of Empress Wu Zetian. By the age of five, in 702 CE, the Tibetan king, Tridu Songtsen, led a military campaign against the Tang-controlled region of Xizhou. Although the Tibetan army achieved several victories, diplomatic channels remained open. In 703 CE, the Tibetan Empire sent envoys with gifts, including 1,000 horses and 2,000 taels of gold, to propose peace and a marital alliance. Empress Wu Zetian agreed to the proposal.
In 704 CE, Tridu Songtsen passed away while campaigning in the western Erhai region (modern-day Yunnan Province). His successor, Tridé Tsuktsen, ascended the throne under the regency of his grandmother, Trimalö.
Princess Jincheng’s Marriage to the Tibetan King
In 706 CE, the first formal peace treaty between the Tang Dynasty and the Tibetan Empire, known as the Shenlong Treaty, was established. In 707 CE, the Tibetan Empire requested a royal marriage alliance, which the Tang Emperor Zhongzong (Li Xian) accepted. In 710 CE, Princess Jincheng was officially granted the title of “Princess Jincheng” and was chosen to marry Tridé Tsuktsen.
In November 709 CE, a Tibetan delegation of 1,000 people arrived in Chang’an (modern-day Xi’an) to escort Princess Jincheng to Tibet. In early 710 CE, Emperor Zhongzong issued an edict emphasizing the importance of peace and harmony, marking the beginning of her journey. After a farewell banquet in Xianyang, Princess Jincheng traveled west under the protection of envoy Yang Ju and arrived in Lhasa, where she married the Tibetan king.
To commemorate this diplomatic marriage, the Tang court renamed Xianyang as “Jincheng County” and granted tax exemptions for local residents for one year.

In a time of fluctuating relations between the Tang Dynasty and the Tibetan Empire, Princess Jincheng’s marriage in 710 AD was a strategic move to cement the alliance. Emperor Zhongzong sent General Yang Jue to escort her to Tibet, a journey that symbolized the diplomatic efforts of the period.

Despite these efforts, Tibetan military incursions continued.
From 714 CE to 733 CE, the Tang Dynasty and the Tibetan Empire engaged in continuous conflicts. Princess Jincheng played a mediating role, advocating for peace between the two empires.
